Struct libbpf_rs::Program

pub struct Program { /* private fields */ }

Represents a loaded Program.

This struct is not safe to clone because the underlying libbpf resource cannot currently be protected from data races.

If you attempt to attach a Program with the wrong attach method, the attach_* method will fail with the appropriate error.

Implementations
